GF-6 satellite remote sensing imagery of Lake Merzbacher

The cover image is the 2-meter resolution multi-spectral standard false-color composite image of Lower Lake Merzbacher, acquired by GF-6 satellite on July 3, 2022. Lake Merzbacher is located at the intersection of the northern branch of the Inylchek Glacier and the southern branch of the Inylchek Glacier in Tian Shan mountain range, with an altitude of about 3300 m above sea level. It is a large alpine glacier lake in the Kumalak River basin, an important tributary of the Aksu River, and consists of two lakes: the upper lake (Upper Lake Merzbacher) and the lower lake (Lower Lake Merzbacher). The upper lake is located in the front of Northern Inylchek Glacier, while the lower lake is an ice-dammed lake produced by the blockage of Southern Inylchek Glacier. The outburst flood caused by the discharge of Lake Merzbacher’s lower lake water is one of the most important flood disasters in Aksu region in China, and has been recorded for hundred years. It mainly occurs from July to September, and affects the infrastructure and the safety of residents along the Kumarik River in China.
